| Polyester Resin + E-glass (Pultruded) | Cost-effective, good mechanical strength | Standard handrails and rails in non-aggressive environments | Lower cost; good strength-to-weight | Moderate chemical resistance; choose vinyl ester for harsher conditions |
| Vinyl Ester Resin | Improved chemical and seawater resistance | Coastal platforms, chemical plants, wastewater | Longer service life in corrosive sites | Higher cost |
| Epoxy / High-Performance Resin | High stiffness and creep resistance | Critical structural posts, heavy-duty applications | Excellent long-term performance | Higher material and processing cost |
| Surface Finish: Gelcoat / Topcoat | UV and abrasion protection | Outdoor handrails and high-visibility areas | Improves appearance and reduces maintenance | Finish selection must match exposure |
| Hardware & Anchors (Stainless / Coated) | Fixing integrity and corrosion resistance | All installations — choose compatible materials | Prevents galvanic corrosion; extends life | Stainless adds cost but reduces lifetime maintenance |
